To all whom it may concern:

Be it known that I, LEONARD BARTLETT, a

' citizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a new anduseful 'Bottle-Seal-Assembhng Ma- 'chine, of which the following is aspecification.

This invention relates to machines for assembling bottle seals in whichrubber gaskets and aluminum protecting disks are used; and has for itsObject to provide a machine of the character described in which themetal sealing caps may be placed, and the rubber gaskets and aluminumprotecting disks areautomatically placed in position within the cap; afurther object being to provide a suitable gasketcutting machine whichwill operate in conjunction with the driving mechanismof the assemblingmachine, and which will cut the rubber gaskets and deposit them withinthe metal cap; a

, further object being to provide suitable -mechanism to cut out andform the alumi nuni disks, and to force the disk when formed into thecap after suitable pasting apparatus has deposited sufiicient paste tosecure the disk to the metal cap, whereby the aluminum disk is broughtinto close contact with the center of the metal ;cap and may be securedthereto by ,the paste.

It is also the object -of this invention to provide simple andcoordinate parts which will work together to make an effectiveassembling machine. I

e invention is illustrated in the accompanying drawings in which- Figure1, is a side elevation of a bottle seal assembling machine constructedaccord ing to my invention; Fig. 2, is a view of the oppositeside of themachine, with the cap hopper and feed mechanism removed; Fig. 3,

is a top plan view of the machine; Fig. 4, is a vertical section of thegasket cutting machine; Fig. 5, is a sectional view thereof on the line5 5 of Fig. 4; Fig. 6, is a secview of the forming and punching die;Fig. 12, is a side elevation of the operating mechanism for the aluminumfeed; and, Fig. 13, is a side view of themain shaft and cams; and Fig.14, is a sectional view of the seal assembled, on a larger scale.

In the drawings, like numerals of reference refer to the same parts ineach of the views; and in practice I provide a frame 15, having a table,or platform 16, on which are mounted the assembling parts herein-v tothe base thereof is mounted a shaft 17, which may be driven by a beltpulley as 18, by which the entire assembling machine may be operated.

The machine is adapted to assemble a seal, such as shown in Fig.,14,comprising a metal sealing cap, as 19, a rubber ringshaped gasket 20,and an aluminum protecting disk 21, with a depressed center 22, adaptedto contact with the center of the cap 19, within the gasket 20, and tobe seecured to said cap by adhesive material, or in any desired manner.To assemble these seals quickly, and in an economical manner, a hopper23, is provided in which the metal caps may be placed, and in whichapparatus of well known construction is operated to feed the caps downthe chute 24, to a rotatable feed wheel 25, within the channel 25, whichcarries the caps around to the wheel 26, having spaced notches, as'27,in the periphery thereof "into which the caps are fed,

vafter described; and-in theframe adjacent I and by this wheel 26,.arefed to the different A parts of the assembling machine in regular anddefinite order.

To operate the parts just described, a shaft 28, is 'pivotally connectedwith the rocking bar 29, the opposite end of which is connected with theshaft 30, which is operated vertically by the cam 31, on the shaft 17.This mechanism operates the hopper feed mechanism 'in a mannerwellknown,

' ing disks placed therein. Consequently, the

parts described thus far have to simply feed these caps to the wheel 26,so as to place a' cap in each notch 27, with the proper side up toreceive the gasket and disk.

' It is one object of this invention to form the metal disk and cut itout, and also form, or cut the rubber gasket as well as assemble theseparts in the cap to form the seal. As the gasket is deposited first, Iwill describe this part at this point, and the other parts of themachine in the regular order in which they operate.

' It will beunderstood that the several parts, or assembling devices,are spaced a suitable distance apart, so that when the wheel 26, is heldstationary by the in 42, engaging successively the holes 43, 1n thiswheel, in a manner well known in such machines, one of the notches willbe directly beneatheach device, and will remain there a suflicientlength of time for each device to operate. 7

B ferring to the gasket forming machine, or device,-this part isspecially shown in a partial view. at the right of Fig. 2, andspecifically in Figs. 4, 5, 6, and 7; and the operating meansspecifically in Figs. 8 and 9. The gasket machine comprises a tube 44,of a size to receive a tubular section of rubber 45, as shown in Figs.5, and 6; and the upper end of the tube 44, is secured in the arm 46,

of the standard 47, and a second arm 48, supports the tube 44centrally-thereof, as

particularly shown in Fig. 4. Slidablymounted on the tube 44, is anannular block 49, which is pivotally connected witha lever 50, which ispivoted at 51, toa cross plate 52, as specially shown in Fig. 8. Thelever 50, is connected with the block 49, by the i link 53, and yoke 54,which is pivoted-at 55, ,to an arm 56, projecting from the arm 46.

The'lever 50, is provided with a depending arm 57, on the lower end ofwhich is a friction roller 58, which is mounted between two guides 59,ona vertically movable block 60; and the upper ends of.the.'guides areconcentrically curved, as shown at 61, whereby'when the block 60,descends until the roller 58, engages the, curved parts of the guides,the roller will be carried laterally, as

willbe understood, and with it the lower end of the arm 57, of the lever50, as will also be understood, causing-the outer end of the lever 50,to descend; and as this end is connected with the block 49, through thelink 53, and yoke-54, the block 49, will be forced downward on the tube44. The slide block'60, is connected with a shaft 62, secured to a strap63, on a cam 64, on the shaft 17, by which this block is moved in theguide frame 65. An annular ring 66, is also slidably mounted on the tube44, and is provided with lugs 67, in which are pivotally mounted thefeed pawls 68, preferably three in number, and substantially triangularin shape, as shown at the right in Fig. 4, with the vertical sideprovided with teeth, as 69,

in order totake a firm hold on the rubber tube. 'Pivotally mounted inthe third corner ofeach pawl is a link 70, the upper end of which ispivotally connected with the annular block 49, and these links, three innumber as shown, form the only connection between the block49, and thering 66, so that in lifting the annular block 49, the ring 66,

will be raised a short distance through the links 7 O, and pawls 68; butthese links being connected with the outer corners of thetriangular-shaped pawls, the pawls will be drawn backward out of theslots 71, in the tube 44. When, however, the annular block 4.9, 'isdriven downward, as previously described, the links will drive the pawlsinward until in tight contact with the rubber tube, and the rubber tubewill be carried downward a short distance with the pawls and ring 66, aswill be understood, to feed the rubber tube the required amount to forma gasket. Mounted on the lower end of the tube 44, is a sleeve 72, onwhich is rotatably mounted a belt wheel 73, secured to a ring 74, towhich is clamped a grooved ring 75, in the grooves of which are mountedblades 76, preferably three in number, and of the form shown speciallyin Fig. 7, each blade having a hooked end '77, in which is mounted aspring 78, whereby the ends of the blades are held normally against thecam ring 79, which is non-rotatable This cam ring is secured to a head80, by posts 81, and is ver- 'to the frame at 83, and carrying afriction roller 84, which engages the cam 85, on the shaft 17, the head80, being sufliciently loose to allow of operation by the lever 82.

In operation the pulley 73, is operated by a belt 86, which engages apulley187, on the shaft 37. When a cap is directly beneath the tube 44,and the rubber has beendriven down the required length to form a gasket,the cam 85 operates to force the head 80, downward, and with it the camring 79, the cam surface of which bears against the hooked end of theblades 76; and as this ring descends, the blades are driven inward intothe rubber tube 45; and as the blades are in the rotatable part, theyare carried around rapidly as they are forced inward, thereby cutting eda' section-of the'rubber tube to'form a gasket; and, as previouslymentioned, the cap being directly beneath, the tube 44, the gasket whencut will drop into the cap, and will be carried forward by the nextmovement of the wheel 26, and another cap will be brought under the tubefor the repetition'of the operation. To insure the positive operation ofthe knives, 1 prefer to rovide a belt tension device, as 86. After idlegasket is deposited in the cap', the cap and gasket are carried forwardto the paste machine 87*, where a suitable amount of paste, or adhesivematerial is deposited in any desired mannerso as to engage the center ofthe cap within the gasket ring; and the cap and gasket are then carriedforward to the aluminum disk former and die. This part comprises a frame87, carrying the sliding head 88, in which is mounted the forming tool89, comprising a spring-controlled contact block 90, and a plunger 91",which forces the aluminum into the cavity 92, to form the projectingportion 22, which afterward engages the center of the cap, as previouslydescribed. After the projection 22, is formed, the aluminum strip 94, isfed forward by the feed rolls 95, which are operated by the awlmechanism shown .in Fig. 12, operated by a plunger shaft 96, connectedwith a lever 97, operated by a cam 98, the awl mechanism in Fig. 1,being indicate by 99. By this arrangement the aluminum is fed forwardstep by step as needed,'

and the required distance so that at the next movement the projectingportion 22, will be directly beneath the punch 100,- and centrallythereof, so that the circular plate 101, of the punch will enter thisprojection, and after the disk is punched out and carried down throughthe die 102, the plate 101, will force the portion 22, into closecontact with the center of the cap within the gasket ring, and thecement, or adhesive materialwill secure this portion to the cap wherebythe rubber gasket will be permanently secured in position. After theseal is assembled, as described, it is carried forward to the chute 103,and a plunger 104, secured to the punch head, will insure thedislodgment of the completed seal, as will be understood. The punch isoperated by a shaft 105, and cam 106, on the shaft 17 As the operationof the several parts has been fully described in connection with eachpart, it will not be necessary to again dee scribe the operation of thecomplete machine further than to state that as all of the parts areoperated by the main driving shaft 17, on which the respective cams aremounted, and adjusted to bring. into action the several arts at theproper time to insure the perfect working of the machine, all

the parts will work together harmoniously and automatically to insurethe production of perfect seals.
